Title: Seismic Resilience of Foundations in Liquefiable Soils Stabilized with Microbial-Induced Carbonate Precipitation (MICP)

Author: Xhunitya Yane, Lenhao Zhou, Ivan Matnez-Vatuena & Dugge Yang

Abstract: Soil liquefaction during seismic events poses a severe threat to shallow foundations, often leading to excessive settlement, tilting, and structural collapse. Conventional ground improvement techniques, such as chemical grouting and deep dynamic compaction, are costly and environmentally disruptive. This study evaluates the seismic performance of shallow foundations resting on liquefiable sandy soils treated with Microbial-Induced Carbonate Precipitation (MICP). The research utilizes Sporosarcina pasteurii bacteria injected into loose, saturated sand models to induce calcium carbonate precipitation, thereby binding soil particles and increasing shear strength. Shake table testing is conducted on scaled shallow foundation models to simulate high-intensity earthquake loading. Sensor arrays measure pore water pressure generation, ground accelerations, and structural settlement across varying levels of MICP treatment density.The experimental data reveals that MICP treatment reduces liquefaction-induced foundation settlement by up to 78% compared to untreated loose sand. .………….. [For more click here]

Title: Multi-Stakeholder construction site layout problem solved with Metaheuristics

Author: Amit Kumar Singh, Shubhendu Amit, Shaishaw Prasun, Purushottam Kumar, MD Shamsher Alam, Amit Kumar Sinha & R Satya Reddy

Abstract: An efficient construction site layout is a critical factor in the success of construction projects because it directly affects safety performance, material handling costs, productivity, and environmental impacts. The spatial arrangement of temporary facilities (TFs) within limited site boundaries must respect technical, regulatory, and neighborhood constraints. This paper addresses the Construction Site Layout Problem (CSLP) from a multi-stakeholder perspective, acknowledging that modern construction environments are ecosystems of diverse stakeholders with conflicting objectives. We formulate CSLP as a multi-objective combinatorial optimization problem and propose a specialized metaheuristic framework to reconcile these diverse interests. The proposed model is validated on a representative construction scenario, demonstrating significant improvements in overall performance, safety, and stakeholder satisfaction..…………..[For more click here]

Title: Automated Concrete Crack Detection and Measurement on Highway Bridges Using Deep Learning Neural Networks and Unmanned Aerial Vehicles

Author: Raziar Wakhah, Chau Chen, Zi Ma & Xingang Xio

Abstract: Traditional manual structural inspections of concrete highway bridges are inherently slow, expensive, and hazardous for field technicians. This research proposes an automated assessment framework that combines high-resolution drone imagery with optimized convolutional neural networks. The system automatically detects, classifies, and maps surface defects like cracking and spalling without requiring physical scaffolding. Advanced photogrammetry algorithms then calculate precise crack widths and depths to evaluate structural integrity in real time. Field testing on active transportation corridors aims to validate the speed and accuracy of this digital pipeline. Ultimately, this study provides asset managers with a scalable, data-driven tool for proactive infrastructure maintenance...…………..[For more click here]

Title: Optimizing Recycled Aggregate Concrete Performance via Nanomaterial Enrichment and Carbon Capture Curing

Author: Gautam Kumar, Vivek Ranjan & Sunita Sarangi

Abstract: This research investigates a dual-treatment approach to overcome the mechanical and durability limitations of Recycled Aggregate Concrete (RAC). While utilizing recycled concrete aggregates reduces construction waste, the high porosity of the old adhered mortar typically compromises the strength of new concrete. This study evaluates the synergistic effects of incorporating nano-silica particles into the mix and subjecting the fresh concrete to accelerated carbonation curing. Experimental testing focused on compressive strength, water absorption, and chloride ion penetration over a 90-day curing period. Microstructural analyses via Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) were conducted to evaluate pore refinement. The results indicate that the combination of nano-silica and carbon curing fills micro-voids and accelerates the formation of calcium silicate hydrate (C-SH) gel. This treatment increased compressive strength by up to 24% compared to untreated RAC, while drastically reducing permeability. Ultimately, this integrated method offers a highly scalable and effective pathway for using fully recycled aggregates in structural applications, moving civil engineering closer to net-zero carbon goals….…………..[For more click here]

Title: Real-Time Urban Traffic Signal Optimization Using Internet of Things Sensors and Dynamic Infrastructure Digital Twin Simulations

Author: Zunghng-Lahng Cung, Zuha Yang & Jumakha Zangu

Abstract: Severe traffic congestion in modern metropolitan areas significantly increases commuter delays, fuel consumption, and localized air pollution. This project introduces an intelligent management system that integrates internet-of-things sensors directly into existing urban transit networks. The gathered real-time traffic data feeds into a dynamic digital twin model representing the entire metropolitan infrastructure. Machine learning predictive algorithms constantly analyze these vehicular patterns to forecast upcoming peak-hour bottleneck formations. The system then automatically adjusts traffic signal timings across connected intersections to maximize continuous vehicle throughput. Microsimulation testing aims to demonstrate a measurable twenty percent reduction in overall commuter transit times….…………..[For more click here]

Title: Evaluating the Mechanical Strength and Durability of Eco-Friendly Concrete Developed From Calcined Clay and Agricultural Waste Ashes

Author: Tarrah Mount Gill & William Tukare Johnson

Abstract: The global manufacturing of traditional Portland cement generates massive carbon dioxide emissions that accelerate climate change. This study investigates a sustainable alternative by substituting thirty percent of cement binder with calcined clay and rice husk ash. Comprehensive laboratory testing will evaluate the resulting compressive, flexural, and tensile strength characteristics over a ninety-day curing period. Additionally, specialized durability experiments will measure the material’s long-term resistance to aggressive chloride penetration and acid attacks. The microstructural density of the hydration products will be analyzed using scanning electron microscopy imaging. This research aims to deliver a viable, low-carbon concrete formula for green commercial building applications………….[For more click here]

Title: Tribological and Performance Insights of Textured Cutting Tools for Metal Matrix Composite

Author: Sunit Awasthi, Saurabh D. Sharma, Manoj Dwsai, Mohar kumar, Alok Kumar & Jayant Kumar

Abstract: Metal matrix composites (MMCs) are advanced engineering materials widely used in aerospace, automotive, and defence industries because of their high strength, stiffness, wear resistance, and thermal stability. However, the presence of hard ceramic reinforcements such as SiC, Al₂O₃, and B₄C makes MMCs difficult to machine, leading to severe tool wear, high cutting temperature, friction, and poor surface quality. To overcome these challenges, textured cutting tools have emerged as an effective tribology-based solution. Surface textures in the form of grooves, dimples, pits, or biometric patterns are introduced on the rake and flank faces of cutting tools to reduce the real contact area, trap wear debris, retain lubricants, and guide chip flow. These mechanisms help in reducing friction, adhesion, cutting force, crater wear, flank wear, and cutting temperature while improving tool life and surface finish. The effectiveness of textured tools depends strongly on texture geometry, orientation, density, and location relative to the cutting edge. Laser surface texturing is the most widely used fabrication method due to its precision and flexibility. ………….[For more click here]
